.. VDISGHARGING ARRANG MENT IN sHARrE-ivnm vrac rriivns "F03 Application filed .April 13, 1928, Serial No 269,830, {and in Sweden 'J jin This invention relates to a discharging arrangement in sharpening machines in which the belt is arranged to .IHOVG the blades 1n horizontal position to a tion on the under part of the belt andin which in the path of the blades a movable member is arranged in such a way, that its movement under the influence of the fedblades causes the blades in horizontal position to be released 10 from the belt in vertical direction.

One embodiment taken as example of the invention is shown in the accompanylng drawings. Herein is Fig. 1 a side View of the Fig. 2 shows the discharging arrangement seen from the side, with the parts in another position than in Fig. 1. Fig. 8 is a section along the line III-III in Fig. '1.

According to Figs. 1-3 the endless belt or chainis indicated by 1. This: is fed in the belt or chain is provided with'jproj ections or At the discharging POSllllOIly which according to Fig. 1 is arranged at the underv which is provided with a bevelled surface 7,

2. A discharging mechanism comprising a conveyor for transporting an article with a hole, a pin upon which the article is adapted to be caught, a support which is movable in respect'to the pin'and upon which the article is adapted to be rested, movable means con-- nected with the support being actuated by the article in passing toward the pin to move the support first into a receiving position then into a release position, and a thrust member acting in conjunction with said support to displace the ar icle from the conveyor a for reception by the pin.

3. A discharging mechanism comprising a movable conveyor having a catching member for engaging the hole of a blade. a pin by which. a blade is adapted to be impaled, means by which the blade is slightly separated from the conveyor during passage toward the pin,
